Embedded Systems In Industrial Control Applications

With the rapid development of computer hardware technology, the applicationsof Embedded System become more and more popularization. At the same time, theapplications of Linux become more and more popularization too. Because industrycontrol is important Embedded System application field, and Linux is a kind of strongdevelopment tool of Embedded System, the project mainly develop an embeddedindustry control system by Linux as mainly tool.The target of this subject is to design and accomplish an industry control systemfor embedded domain. Based on the deeply analysis and research of function andmechanism of several current popular embedded develop tool, we make sure about thetechnology route and requirement. Then on the basis of digesting the key technologyand develop tool, we have use several key technologies and accomplished theembedded industry control system, whose function and performance is advanced.The main contents of paper include:1.Have provided the analysis of requirements on industry control system, andprovided the development and implement of it.2.Provided the method of design and implement to improve the system'sreal-time capacity by method of modify the system timer and interrupt,modifiesof process's statues,communcation in processes and scheduling of processes.3.Have provided the design and implement some of hardware driver and somedriver of network devices.
